What didn't work?

Frequent disconnecting while accessing eduroam network (every 2~3 minutes) and can't reconnect unless I disable and re-enable wifi. Every other home/work wifi work perfectly.

What did you try?

Tried other versions of the driver and made sure the eduroam network was properly configured.

Error code:

#block ends

Hi I have known this issue for a while . Although I don't think this is only related to the open source driver developed by @neurobin .

In most of the Universities where I have been, the chance of this issue to happen is increases if one of these two factors occurs :

Since you seem not be able to connect with eduroam whenever you want, I think you should change the way of how your computer deals with the tcp connection when you are connected to Eduroam. Generally your computer will use the default congestion control algoritm Cubic. Run : sysctl net.ipv4.tcp_congestion_control , to check if the congestion control algorithm is Cubic. If it is the case, I suggest you to either change it to Westwood or BBR. As you may know Eduroam is a highly congested network, so this is a easy trick to deal with this problem.You can do it by running :

Can confirm this issue. My solution was to 'lock' my connection to only one access point instead of jumping between them. Dont remember how i did but that was the only solution working for me. Frustrated and I really hate this Mediatek card. After i while i bought an external usb wifi. Made it possible for me to spend my time on something more relevant than trying to solve this kind of crap problems all the time...

I have exactly same problem. I have a hard time linking to campus wifi(eduroam, peap etc...), or frequently disconnecting.. Can someone give me more solutions.. Thanks a lot!

my linux version: 4.4.0-116-generic (ubuntu 16.04)

@deeperlearner Everyone is avoiding to use this card . My solution was to buy a new network card which is fully supported in Linux.

@Jpfonseca Could you suggest some alternative cards that support Linux. I am preferring Intel 1760, but I heard that it does not support Linux

Jpfonseca commented 4 years ago

Look for a Intel 7260, it's Linux compatible and supports 5GHz

@Jpfonseca I did some research about Intel 7260 and I found that this Wifi card has several issues. Have you experienced any issue with it? (i.e. connection constantly dropped)

Jpfonseca commented 4 years ago

So far no issues. But I now have two antennas instead of one, because this card has 2slots for them.
